TUBULAR LANTERN.

SPECIFICATION forming partof Letters Patent Ne.A 365,605, dated June 28, 1887.

Application Iiled July 7, l88d. Serial No. 207,303. (No model.) u

the globe is raised from the burner, thereby giving access to the wick for trimming, lighting, extinguishing, Src.

The object of my invention is to improve the devices whereby the parts of the lantern are connected and the globe is held in place.

My invention consists, to that end, of the improvements, which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings,`Figure -l is a side elevation lof the lantern provided with my improvements. Fig. 2 is a similar view showing the globe raised. Fig. 3 Vis a horizontal section in line w x, Fig. 1. Fig. 4 is a vertical section 4in line y y, Fig. 1, on an enlarged scale. Fig. 5 is a side elevation of the lower part of the lantern at right angles to Fig.v1. Fig. 6 is aiperspective view of one of the spring-guides. Fig. 7 is a vertical section in line z z, Fig. 1.

Like letters of reference refer to like parts in the several figures.

' A represents thebase ofthe lantern, containing the oil-*pot A', the airchamber B resting on the same, and the burner O.

b b represent the short horizontal portions of the air-supply tubes, which are secured to the sides of the air-chamber, and which have their outer and upper portions cut away to form outwardly-projecting semicircular bottom portions, b', which are open at the top.

D D represent the side tubes connected at theirupper ends to a vertical tube, which is provided at its lower end with a bell or funnel, d', in the usual manner.

E E represent the horizontal lower portions of the side tubes, which open inwardly or toward the air-chamber and rest in the semicircular portions b of the base when the globe is lowered. The joint between Vthe horizontal tubes E and b is covered by curved shields E', which are secured to the upper sides of the tubes 'E and protect the joint against rain, dust, &c.

F F represent bent bridge-pieces secured with their ends to the horizontal tube portions A' portv for the plate G when the latter is in a,

horizontalposition, as represented in Fig. 5. The bridge-pieces .F F hold the burner securelyin its seat and prevent it from dropping out when the globe is broken, thus preventing accidents from this cause.

-I-I represents the globe, and h the annular spring-catch secured to the under side of the bell d', and holding the upper end of the globe in the usual manner. 1

I represents spring-guides secured to the ba'se of the'lantern and embracing the lower portions of` the side tubes, so as to guide the same in their movements toward and from the base.- Each guide I is bent of a single piece of wire, which is secured with its lower ends to the base of the lantern. Each guide I is composed of upright arms t', arranged on the front and rear sides of thel same side tube, a horizontal bow, i', extending outwardly from the upper ends of the arms i and bearing against the outer side of the side tube, and coils i2, connecting the lower ends of the arms i with the ends i3, which are secured to the base of thev lantern. The coils i2 hold the bows i against the slightly-inclined side tubes as the same are raised or lowered.

J represents a wire bail secured with its lower looped ends, jto the upper ends of the guides I, and resting with its upper portion on the top of the central tube, d, when the globe is lowered, as represented in Fig. vl. The side portions, j', of the bail pass`through guideloops K, secured to the inner sides of the tubes D. 4 The upper portion ofthe bail J is locked on the tube d by a projection, l, formed on the ICO top of said tube. The coils i2 of the guide I permit the bail J to yieldv and pass over the projection Z and dranv the bail tightly against the tube d after it has passed over the projection, thereby securely holding the upper and lm ver portions of the lantern together. In this respect the guides Ioperate as springs for the bail J. Upon disengaging the bail J from the tube d the upper portion of the lantern eau be raised from the base, as represented in Fig. 2, thereby exposing the burner-cone and affording access to the Wick for'trimming, lighting, and extinguishing, and permitting the removal of the burner from the oil-pot. The upper portion of the bail J is provided with athumbpiecc, m, for conveniencein handling it.

l claim as my inventionl. The combination, with the base-of the lantern,provided with tubes b, of the vertically-movable side tubes, a globesupport secured to the side tubes, and the springguides I, secured to the base and provided with bows i', which embrace the side tubes, substantially as set forth.

2. The combination, with the base of the lantern, provided with tubes b, and the verticallymovable side tubes provided With a globe-support, of the Wire guides I, scoured to the base, and each composed of upright side ar1ns,17, bows i', and coils 17"', substantially as set forth.

8. The combination, with the base of the lantern, provided with tubes I), and the verticallymovable side tubes provided with a globe-support, of spring-guides I, secured to Jro adapted to engage behind the projection l,

substantially as set forth.

5. The combination, with the base A, provided with a burner, C, ofthe vertically-movable side tubes, D, a bridge-piece, F, connecting the side tubes on one side of the burner, and provided with a hinged plate, G, and a bridge-piece, F', connecting the side tubes on the other side of the burner and forming a support for the plate G, substantially as set forth.

6. The combination, with the base A, provided With an air-chamber, B, and horizontal tubes b, having semieireular bottom extensions, b', of the verticallymovable side tubes, D, having horizontal lower portions, E, adapted to rest in the extensions b', and provided with protecting-shields E, substantially as set forth.

XVitness my hand this 2d day of July, 1886.
